Data Capacity: Unleashing the Power of Data Transmission

At the heart of submarine cables lies their extraordinary data capacity. The latest cables have evolved to transmit an astonishing 160 terabits per second (Tbps) of data, capable of transmitting vast amounts of information at lightning-fast speeds. To put it into perspective, this is equivalent to transmitting over 5,000 high-definition movies every second. Such massive data capacity ensures that our ever-growing appetite for data-intensive applications, streaming services, and real-time communication can be satisfied.

Global Connectivity: Bridging Continents and Cultures

Submarine cables are the physical conduits that connect continents and countries, forming a global network spanning over 1.2 million kilometres across the ocean floor. Over 200 countries and territories are interconnected through this intricate web of cables, facilitating seamless communication and fostering cultural exchange. This vast network empowers individuals, businesses, and governments to transcend geographical boundaries and collaborate effortlessly in the digital realm.

Internet Traffic: Carrying the Pulse of the Digital World

When you send an email, stream a movie, or browse the web, the chances are that your data travels through a submarine cable. These undersea lifelines carry an astounding 99% of all international data traffic, making them the backbone of our global internet infrastructure. Every video call, every online transaction, and every social media post rely on the reliability and capacity of submarine cables, ensuring that the pulse of the digital world beats without interruption.

Economic Value: FuelLing Growth and Prosperity

The economic significance of submarine cables cannot be overstated. Estimates indicate that the global submarine cable industry generates over $10 trillion in economic value annually. These cables serve as catalysts for economic growth, fostering innovation, enabling trade, and facilitating the development of digital economies. From multinational corporations to small businesses, submarine cables underpin global connectivity, empowering enterprises to engage in data-intensive activities such as e-commerce, cloud computing and online banking, to name just a few.

Length of Cables: Awe-Inspiring Engineering Marvels

The sheer length of submarine cables laid on the ocean floor is awe-inspiring. For example, the recently announced 2Africa cable will stretch a staggering 45,000 kilometres, circumnavigating the continent and opening up new possibilities for connectivity. These feats of engineering involve precise planning, advanced technology, and careful navigation of underwater terrains. This record breaking cable has already landed in Djibouti and will be our 10th submarine network once it goes live in 2024.

Lifespan: Navigating the Depths of Time

Despite the challenging conditions of the marine environment, submarine cables have proven to be resilient and long-lasting. With an average operational lifespan of 25 years or more, these cables are built to withstand the rigours of the ocean depths and ensure uninterrupted connectivity. Regular maintenance and monitoring are essential to keep the cables in optimal condition, safeguarding the reliable transmission of data and upholding the trust placed in these vital communication arteries.

Cost: Investing in the Future

Laying and maintaining submarine cables is a significant investment. The cost of laying a single kilometre of cable can range from $20,000 to $250,000, depending on various factors such as depth, distance, and the technology employed. These substantial financial commitments underscore the importance placed on global connectivity and the recognition of submarine cables as indispensable infrastructure for our digital age. The economic and societal benefits they provide far outweigh the initial investment, making them a vital component of our modern world.

Importance for Businesses: Empowering a Digital Economy

Submarine cables are essential for businesses, acting as enablers of global connectivity and serving as the backbone of the digital economy. E-commerce platforms rely on these cables to facilitate secure online transactions and international trade. Cloud computing services utilize submarine cables to store and access vast amounts of data seamlessly. Online banking, financial transactions, and real-time collaboration among global teams are made possible by the reliable and high-speed data transmission provided by submarine cables. Furthermore, supply chains spanning continents are tightly integrated through these cables, ensuring efficient coordination and delivery of goods and services.

Hopefully, the above has give you a glimpse of the importance of submarine cables. It is for these reasons we continue to invest in our network – currently there are 8 Operational submarine cable systems and 5 on-project cable systems.
